They're padded with a margin that favors the house. This Connector changes that by letting your agent do the math for you in real time. Instead of guessing how much of a cut the bookie is taking, you can ask your agent to strip that margin away and tell you what the actual probability of an outcome is. It's a huge step up for anyone who wants to base their decisions on hard data rather than just what's on the screen. You can feed in any set of American odds and get back the underlying market price. It takes the guesswork out of finding value and lets you focus on your own projections. Finding these tools in the Vinkius catalog makes it easy to plug this directly into your existing research workflow. You get a clear look at the fair market, which is the only way to know if a bet actually has an edge. ## Tools ### calculate_overround_percentage Determines the total margin the bookmaker is charging on a set of odds. It helps you see the house's cut clearly. ### get_raw_probabilities Converts American odds into unadjusted implied probabilities. This shows the probability before any adjustments. ### get_true_probabilities Removes the bookmaker's margin to provide fair market probabilities. This is the core calculation for finding value. ## Prompt Examples **Prompt:** ``` What are the true probabilities for a game where the odds are -110 and +110? ``` **Response:** ``` The true probability for both outcomes is **50.0%**. Here is the breakdown: - **Raw Probability**: 52.38% - **Overround (Vig)**: 4.76% - **Fair Market Probability**: 50.0% ``` **Prompt:** ``` Calculate the overround for these odds: [-150, +130, +500] ``` **Response:** ``` The total overround (vig) for these odds is **6.45%**. This means the bookmaker is taking a 6.45% cut from the total pool of these three outcomes. ``` **Prompt:** ``` Convert these odds to raw probabilities: [-110, -110] ``` **Response:** ``` The raw implied probabilities are **52.38%** and **52.38%**. These numbers represent the probabilities before removing the bookmaker's margin. ``` ## Capabilities ### Strip bookmaker margins Remove the house cut from American odds to find the actual fair price. ### Calculate overround percentage Determine the exact percentage of the margin being charged on a set of lines. ### Convert to raw probabilities Turn American odds into unadjusted implied probabilities for a baseline. ### Identify fair market odds Get the true probability of an event without any bookmaker bias. ### Compare market value Compare de-viggered odds against your own personal projections for better bets. ## Use Cases ### Finding Value A bettor asks the agent to check if a -110 and +110 line is fair.

They ask the agent to de-vigger the odds instantly to see the real chance. ## Benefits - Stop guessing the house's cut by using calculate_overround_percentage to see the exact margin. - See the raw numbers first with get_raw_probabilities to understand the starting point of the odds. - Get the actual fair price with get_true_probabilities for more accurate betting decisions. - Identify value faster by comparing de-viggered odds against your own personal models. - Save time on manual math by letting your agent handle the probability conversions instantly. ## How It Works The bottom line is you get the real probability of an event without the house's cut. 1.
